EUROPEAN SEISMOLOGICAL DATA BANK

Objective

TO PROVIDE SEISMOLOGICAL DATA TO THE POTENTIAL USERS IN THE EC FOR SPECIFIC STUDIES.

THE DATA BANK WOULD INCLUDE :
-EARTHQUAKE DATA SENSU STRICTO
THE FIRST PHASES IN IMPLEMENTING THE DATA BANK CONCERN THE EARTHQUAKE DATA PROPERLY.THOSE HAVE BEEN TENTATIVELY DIVIDED IN "LEVELS":

I- LEVEL 1A DATA ("DERIVED PARAMETERS") : EARTHQUAKE PARAMETERS WHICH CHARACTERIZE AN EARTHQUAKE AND RESULT FROM COMPUTATIONS CONDUCTED ON ELABORATED DATA (LEVEL 1B DATA), EXAMPLES : FOCUS COORDINATES, MAGNITUDES, FOCAL SOLUTIONS, ...;

II - LEVEL 1B DATA ("READ PARAMETERS") : DATA ELABORATED FROM OBSERVATIONAL DATA (LEVEL 2 DATA) AND USED TO PRODUCE DERIVED PARAMETERS (LEVEL 1A DATA) EXAMPLES : PHASE READINGS, AMPLITUDES, PERIODS, ...;

III - LEVEL 2 DATA : OBSERVATIONAL (RAW OR STANDARDIZED) DATA FROM WHICH LEVEL 1B DATA ARE READ, EXAMPLES : WAVEFORMS, ... ;

IV - LEVEL 3 DATA : ANCILLARY DATA, EXAMPLES : LOCATION OF STATIONS, TYPES OF INSTRUMENTS IN A STATION, STATION RESPONSE, ...
LEVELS 1A AND 1B INCLUDE DIGITAL DATA, WHICH SHOULD BE ACCESSIBLE ON A QUASI-REAL TIME BASIS FOR THE USER. LEVEL 2 INCLUDES MUCH MORE VARIED DATA : DIGITAL WAVEFORMS ACQUIRED BY MODERN INSTRUMENTS, ANALOGICAL (EVENTUALLY DIGITIZABLE) WAVEFORMS RECORDED BY STANDARD (OR ANCIENT) INSTRUMENTS, ANALOGICAL MACROSEISMIC INFORMATIONS, ETC... ; IN ANY CASE DIGITAL LEVEL 2 DATA ARE MUCH MORE BIT-CONSUMING THAN THE TWO FIRST LEVEL DATA ; ACCESS TO DIGITAL LEVEL 2 DATA BY USERS COULD CERTAINLY BE MORE OR LESS DELAYED, AND OF COURSE THIS WILL BE THE RULE FOR NON-DIGITAL LEVEL 2 DATA.
AT THE VERY BEGINNING LEVELS 1A AND 1B WILL BE MAINLY CONSIDERED, EVEN THOUGH LEVEL 2 WILL NOT BE IGNORED COMPLETELY (SPECIALLY IN ESTABLISHING CLOSE CONTACTS WITH BROAD-BAND SEISMOLOGISTS AND THEIR OWN PROJECTS PART OF LEVEL 3 WILL ALSO BE A NECESSITY (LOCATION OF STATIONS, FOR EXAMPLE).
